October 29, 2009 - Dean Kamen is a phenomenon. He has invented, among other things, a wearable medication pump, a portable dialysis machine, the Segway PT, an electrical generator that can run on cow dung and produce potable water on the side, and a fully-functional prosthetic arm. He holds more than 440 foreign and domestic patents and counting. And 18 years ago, he launched FIRST (For Inspiration and Recognition of Science and Technology), an annual competitive challenge to thousands of children from ages six through high school.
